Gomod2nix with go workspaces

I’m trying to use gomod2nix to build a simple http server that listen to a requests. Everything works well with my local modules. go run and nix run works perfectly, however when I add an outside module, go run works but nix run stop working. This is what I get after using an external module and trying to build/run the application with nix:

error: builder for '/nix/store/192rxacfr8al42fd0zaq74wk8dcqbh0g-sim-cards-bot-0.1.drv' failed with exit code 1;
       last 10 log lines:
       > Running phase: updateAutotoolsGnuConfigScriptsPhase
       > Running phase: configurePhase
       > Running phase: buildPhase

       > go: inconsistent vendoring in /build/bot:

       For full logs, run 'nix log /nix/store/192rxacfr8al42fd0zaq74wk8dcqbh0g-bot-0.1.drv'.

After reading the output I tried to add the -mod=readonly and -mod=mod. to the default.nix but it gets the same output.

{ pkgs ? (
    let
      inherit (builtins) fetchTree fromJSON readFile;
      inherit ((fromJSON (readFile ./flake.lock)).nodes) nixpkgs gomod2nix;
    in
    import (fetchTree nixpkgs.locked) {
      overlays = [
        (import "${fetchTree gomod2nix.locked}/overlay.nix")
      ];
    }
  )
, buildGoApplication ? pkgs.buildGoApplication
}:

buildGoApplication {
  pname = "bot";
  version = "0.1";
  pwd = ./.;
  src = ./.;
  modules = ./gomod2nix.toml;
  ldflags = [
    "-mod=mod"
    "-mod=readonly"
  ];
}

Any help would be much appreciated it!!!
